I do have installed alsa-utils, alsa-lib alsa-oss,and i have alsa in the DAEMONS array. i can use alsa and oss whit wine for example, i can listen to music in amarok, all working great, but whit mplayer i cannot do anything. The strangest thing, was that it was working all good yesterday, i was able to access alsamixer and everything, and today found this error (wich i did had before and i dont know how i got it working)

Get rid of those modprobe.conf lines and see if that improves anything.
